Abstract

The utility model provides a clip-type double-edge V-shaped groove slotting tool, belongs to the technical field of mechanical working tools and aims to solve the problems that the conventional single-edge slotting tool is low in machining efficiency and high in using cost. A knife bar consists of a front knife bar and a back knife bar which are integrated; a blade consists of a knife handle and a knife head which are integrated; the front end surface of the front knife bar is provided with a slot matched with the knife handle; a cross section of the back knife bar is rectangular, and the knife handle is arranged in the slot of the front knife bar and tightly fixed on the knife bar by a tightening bolt; a protruding platform shoulder of the blade is pressed on the outer circular surface of the front knife bar; two end-to-end V-shaped edges are machined on the front end surface of the knife head along the width direction of the knife head, and the two V-shaped edges are symmetrically arranged relative to the longitudinal center line of the blade; and a V-shaped slot is formed between the two V-shaped edges. The slotting tool provided by the utility model is used for machining anti-skid slots of chuck jaws of machine tools. When the tool cannot be ground or chipped any longer, the tool can resume work just by replacing the blade, so that the tool is unnecessarily wholly scrapped, the using cost of the tool is greatly lowered, and the machining efficiency is improved.

Description

A kind of clip type twolip V-type groove slotting tool

Technical field

The utility model relates to a kind of clip type V-type groove slotting tool, belongs to the machining tool technical field.

Background technology

V-type groove slotting tool is the dedicated tool that is used for machining tool chuck jaws anti-slip tank.The V-type groove slotting tool that uses at present is overall structure single-blade slotting tool, uses this slotting tool can only accomplish the processing of an anti-slip tank at every turn, and working (machining) efficiency is low; And because this single-blade slotting tool is an overall structure; When cutter again behind reconditioning or the tipping, can only scrap processing, the cutter cost of use is high.

The utility model content

The purpose of the utility model provides a kind of clip type twolip V-type groove slotting tool, to solve the existing problem that single-blade slotting tool working (machining) efficiency is low, the cutter cost of use is high.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the clip type twolip V-type groove slotting tool of the utility model, and said slotting tool comprises knife bar, blade and holding screw; Knife bar is made up of the preceding knife bar of processing one and back knife bar; Blade is made up of the handle of a knife of processing one and cutter head, is processed with the slot that matches with handle of a knife on the front end face of preceding knife bar, and the cross section of back knife bar is a rectangle; The junction of cutter head and handle of a knife is provided with the boss shoulder; Before handle of a knife places in the slot of knife bar, tightly on knife bar, take on and lean on the periphery of preceding knife bar by the boss of blade through holding screw for handle of a knife; The front end face of cutter head is processed with end to end two V-knife swords along the width of cutter head; Said two V-knife swords are symmetrical set with respect to the longitudinal centre line of blade, form a V-type groove between two V-knife swords, and the spacing between two V-knife sword tops is 8mm.

The beneficial effect of the utility model is: the clip type twolip V-type groove slotting tool of the utility model can be accomplished the processing of two anti-slip tanks at every turn, compares working (machining) efficiency with cutter and doubles with former.When cutter again behind reconditioning or the tipping, the blade that only need more renew gets final product, and need not cutter integral body and scraps, and greatly reduces the cutter cost of use, has improved working (machining) efficiency.But also can be according to the material of different processing components, different machining states, the preferred blade material improves machining status.
